Covestro sharpens the focus on LED technology

Shining a light on materials for LEDs

These are challenging times for municipalities, which must juggle multiple priorities, including improving public safety and reducing energy consumption. Achieving these objectives is even more difficult as many municipalities are operating under reduced budgets.

Using Makrolon® LED polycarbonate grades, Covestro and Hella developed street lighting tailored to improving public safety and reducing energy consumption.

Task

These are challenging times for municipalities, which must juggle multiple priorities, including improving public safety and reducing energy consumption. Achieving these objectives is even more difficult as many municipalities are operating under reduced budgets.

Challenge

Many municipalities are choosing to implement LEDs in street lights. Targeted bundling and guidance of the LED light using special optical lenses helps to ensure or even improve vehicular and pedestrian safety. A high-performing material was needed to deliver the properties needed to optimize LED lighting.

Solution

Lighting manufacturers depend on Covestro’s portfolio of specially developed LED grades of Makrolon® polycarbonate to meet their needs for replacement lamps and next-generation luminaries. Hella turned to Covestro and its LED polycarbonate for help developing its Eco StreetLine street lamps. The lights utilize energy-efficient LED technology and can be dimmed by as much as 50 percent. The long service life of the LED modules – 12 years or 50,000 hours – helps reduce operating costs.
